SAN FRANCISCO (AP) — San Francisco, say goodbye to those squeaky, Styrofoam-like coffee cups that have long been a staple of picnic outings. In fact, people in San Francisco won’t be able to buy polystyrene foam coolers, kiddie pool toys or packing peanuts after supervisors approved a measure in June that goes far beyond the prohibition on foam food carryout containers in effect in dozens of cities and counties. Environmentalist are cheering San Francisco’s ban as the most comprehensive by a large U.S. jurisdiction on the cheap insulating foam that cushions goods and keeps drinks hot or cold.
